This task must be operated by trained technicians that are certified by Lenovo Service. Do no attempt to remove or install it without proper training and qualification.
When the server has an LACM module (close-loop cooling module) installed, you must apply for a handle first if you need to install or remove the processor board, I/O board, and processor. However, while replacing the old LACM module with a new one, you do not need to apply for a handle as the new LACM module contains it.
